IMPROVEMENT iN VMACHlNES. FOR WINDING BQBBINS.

The Schedule referred to in these Letters Patent and making part o' the same.

I, FRANKLIN H. MonRrLL, of the city and county of Philadelphia, and State of Pennsylvania, have 'invented a new and useful Improvement in Machine for Winding Bobbins, of which the following is a specification.

Nature and Objects of the Invention.

This invention relates to certain improvements on the machine patented by me under date of 'September 2l, 1869, N o. 95,034, in which a variable rotary motion is 'given to 'the bobbins through a vheart-shaped gear, the object of which is to4 cause the-bobbins to revolve slower while theyarn is passing onto the base of the' cone part, and with increased velocity while passing to the apex of the cone part of the bobbins.

In my former patent a diliculty was .experienced with thebelt which communicates motion to thc spindle-driving cylinder. This Ybelt was liable to slip and lose motion as the speed increased, and, consequently, cause a lost motion of. the bobbins, thus preventing the yarn from windingas closely and firmly as desirable. To overcome this I dispense with the said belt,

p and employ a series of compound gear-wheels, so ar' ranged, 1n connection with the heart-shaped gear, as

to produce an increased number of revolutions of the cylinder andspm'dles while the heart-gear is making one. The traverse mechanism is arranged in such a manner as to move slower while the yarn is passing over the large part of the bobbin, and faster when passing over the small part thereof'.`

.Description of the Accompanying Drawing.

General Description.

The heartshaped gear H is applied to the swinging arm A, and islocated between the pinions P and P', fig. 2,- one' placed above itA and the other on the shaft E, immediately below it.

The pinion P transmits motion, through the gearing R R, to the shaft S of the traversing-frame.

vThe mechanism for producinga more positive motion, and to compensate for the lost motion, which might otherwise occur with the belt before alluded to,

consists of the. bevel-gear wheels, G, G1, G, and G3, vwhich are placed in the interior of a drivinglpulley, N, 3.-

gThe axes a and a. ofthe wheels Gjaud G1, which are at right angles to the axes of the wheels G2 and G2, are secured to the hub and to the rim of the pulley; and the wheel G2, provided on its hub with the pinion P', is placed loosely on the shaft E, while the wheel G3 is keyed to and revolves with the shaft.

The pulley N is made with double faces, d and d', of a large and small circumference, over oueof which, cl', is passed the belt for giving motion to the machine; and on the face d is placed an intermediate belt, J, which also passes over a pulley, N1, and communicates motion to the pinion P, iig. 2, secured-to i'tshub.

A loose pulley, N2, iig. 3, is also placed on the shaft E, and upon it the, driving-belt is to be shifted at will.

Motion is transmitted from -the pinion P through the gearing R R to the shaft S of the traversin g-franie.

The said shaft has secured on it two heart-shaped cams, C and C', gs. 4 and 5, which are located between axed and movable point, vplaced on the inside ofeach ofthe traversing-bars F and F'.

The compound gear, arranged as shown at fig. 3, will produce' 'rapid revolutionsv of the cylinder K and the spindles T, While the heart-shaped gear is moving the pinion P at a slow rate of speed.`

The pulley N is driven at the same rate. of' speed under all circumstanees,'and the pinion P', which plays into the teeth of the heart-gear, and is loose on lthe shaft E, receives a motion through the Abelt J, pulley N1, pinion P, and heart-shaped gear, and conveys it, by means of the-bevel-gear G2, to the wheels G, G, and G3.

When the heartshaped gear, during its revolutions, has reached the position showniu iig. 2, it will-be seen that the leverage j; between the center of motion of it and the pinion P', will be small, while the leverage f', between the pnionP and the center bf motion, will be greater; consequently, the speed of the pinion Pf will be increased, which will therefore cause the gearwheels Gand G1 to revolve faster on their own axes a and a', thus revolving the shaft E and cylinder K faster than at other times. The thread is now winding onto the small part ofthe coneon the bobbin.

When the leverage is greater betweenthe'pinion P and the center of motion of the heart-gear the pinion will be caused to revolve more slowly, which produces a decreased number ofrevolurions of the bevel-wheels G and G1 andas these wheels not only revolve on their own axes, but are carried aronndin the same direction with the pulley N, (which is loose on the Sheila) they will cause a decreased number of revolutions of the' .shaft E and cylinder The traversiugbars are now traveling at a slower speed, and the yarn is winding' upon the large part of the bobbins.

The cams C and C' placed on the shaft S of the traversing-frame, as shown in gs. 4 and 5, Work between fixed studs, V and V', and movable bolts, W and W', placed ou the inside of the traversing-bars F and F'. The sliding bolts W and VW' are surrounded by coiled springs placed in casilngs Y andY, secured to the inside of the bars F and F. points, Whichare constantly in contact with the cams as the bars slide in and out. l

The object in arranging these points thus is to allow a free. movement of the cams between the studs V and V and movable bolts W and W', said cams being of such a shape as to give a gradual increase of speed to thetraversing-bars and thread-guides, to correspond With theincreasing revolutions of the bobbins While the thread is jpassing from the large part of' the cone onthe bobbin to the small part thereof'.

The coiled springs surrounding the bolts W and W are-of-'sueient' .elasticity to hold the bars F and F- backward, and,at thev same time, lto permit the They'thus form movable freely around. A

The xed studs V and V' arey thus also retained constantly' in contact With the revolving cams, and, as they (the cams) turn from the heel to the point upon the said studs, they produce a gradual increased m0- tion of the traversing-bars, and a decreased motion as they turn from the point toward the heel.

I claim as my invention- Y in combination with the heart-shaped gear H, pinionsV P P', pulley N1, and belt J, in 'the manner and for the pu'rposehereiu specified. Y 2. The combination, with the cams G G and traversing guide-bars F F', of the xed studs VV, sliding bolts W purpose herein described.
